I read this article in our paper. They were good enough to link the actual study.

Very cool stuff.

From this link we see that a chemical which is only produced by life here on Earth, has been found in the clouds of Venus. Because the atmosphere of Venus is much larger than the Earth's atmosphere it extends to heights many times higher than clouds here on Earth. At the height this chemical was found temperatures average about 85 degrees F, about 29 degrees Celsius, very present indeed :)

 

If it is a sign of life, that floating bacterial life is basking in very pleasant weather and with atmospheric pressures not that different from the surface of the Earth. The question would then be, is this life similar to bacterial life on Earth or not? If so it originally could have come from the Earth's atmosphere by some means, or even that Earth's life could possibly have come from Venus.

 

I think the odds are that there is another explanation for this chemical in the upper atmosphere of Venus, but in time we can bring back quantities of compressed gas from the atmosphere by robotic means and return them to Earth without ever having to land on the hotter-than-hell planet (about 900 degrees F).

 

Such a mission would be immensely interesting for planetary biologists and countless others including us  X-image.png

I found this link proposing that early Martian life, if any, could have used sulfur and solar energy to produce food. In the Martian atmosphere there is a great deal of sulfuric acid which rains down about half way to the surface before it evaporates then rises again in a seemingly never ending cycle. The possible atmospheric life of this OP could use the sulfur in this acid for its metabolism.

My editing function isn't working. When I said Martian atmosphere and life above I meant Venusian life.

Here's a good link explaining the details of possible life existing in the clouds of Venus. One might note that even if there is no existing life in these clouds now in that there probably is another explanation for the observed phosphere, we could still likely engineer life that could live there. This could be part of a long term plan to terraform Venus to have more earth like conditions. Enough of the right kind of quickly multiplying bacteria in the atmosphere could block out more of the sun cooling down the planet somewhat. Next the bacteria could eat up much of the atmospheric CO2 causing dead bacteria to fall to the surface as hydrocarbons and future fertilization for crops . A less dense atmosphere would have less of a green house effect.

Although this is just a board game and science fiction now, it has the possibility of becoming reality some day. "Terraforming Mars and Venus next."

I guess there's at least two pretty glaring take away's. One is that if true, life will pop up where ever it can pop up. Another is that life will transfer between planets - if that's the case and our upper atmosphere seeded life over to Venus somehow. It just seems to point towards the veracity of life which ever way it would have got there. The same with the prospects of life on moons below ice sheets and the other scenarios. If it's there, life must be pretty god dammed certain to pop up where it's possible for life to pop up. And pushing more towards mundane in the grand scheme, more so than extremely rare as once thought. I'd argue that the Copernican principle should apply to life if this is how it actually works.

 

We wouldn't be as special as previously and commonly assumed, surprise everyone!!!

 

Who couldn't see that one coming???

 

No privileged place in the universe, again........

Here is a cute 11 minute video by a professor talking about phosphine and Venus
